2. Do you expect |ATƒus| or |AT vap| to be larger for the same increase in pressure?

Departmental Problems for Chapter 5: Gases In the 2015 AFC championship football game, it was alleged that the New England Patriots ber the rules by using underinflated footballs. NFL regulations require footballs to be inflated to between 12.5 and 13.5 psi (psi = pounds per square inch). [Note: this is gauge pressure, not ab- solute pressure.] One football actually used in the game was measured to have a pressure of onl 10.5 psi (gauge). One of the Patriots' coaches later alleged that the explanation was due simply gas behavior: pressure decreases as the temperature decreases. Let's examine that last claim. Suppose that the football remained sealed and nearly rigid (i.e. the volume and moles of gas within the ball did not change). A nearby airport measured the air pressure at game time to be 100.95 kPa. The temperature on the field at the start of the game was 51°F. Suppose that the ball was originally inflated in the locker room to the minimum pressure of 12.5 psi (gauge). In order…

The partial pressure of O2 in the atmosphere at sea level is 21.3 kPa.  What is the partial pressure of O2 on the top of a mountain, where the atmospheric pressure is 89.7 kPa? [Atmospheric pressure at sea level is 101.3 kPa.]

Iodine, I,, is a solid at room temperature but sublimes (converts from a solid into a gas) when warmed. What is the temperature (in K) in a 77.0 mL bulb that contains 0.284 g of I2 vapor at a pressure of 0.466 atm? K

At what pressure in atm does ethane (C₂H₆) have a density of 37.2 g/L at 35.4 °C?

At what pressure does butane (C4H10) have a density of 47.2 g/L at 39.5 °C?

An unopened can of soda has an aqueous CO, ooncentration of 0.21 M at 25.0 °C. What is the partial pressure of the gas in the can in torr? The Henry's law constant for CO, at 25 °C is 3.4 x 10 mo/L-atm. • Vlew Avallable Hint(s) O 6.2 torr O 8.2 x 10-3 tor O 5.4 torr O 4.7 x 10° torr
